Dangerous Cargo opens up with Jane giving a briefing of the mission to Case and Trent as a boat takes them silently into the Russian occupied port. The group sneaks into the seaport, where Case slices a fence so that the team can move forward. The group takes cover as a patrol passes through, and Jane orders the team to hold their fire until he gives the go. After the patrol of four Russian separates, Jane and Trent eliminate two of the Russians.

Trent must then hack a computer before the group continues forward. Trent uncovers a manifest that Jane reveals as the manifest to a WMD. Russians, having heard the gunshots, begin to pour onto the dock. The team fights past the hostiles and hacks into the security system of the dock's warehouses.

The team fights through the first room of the warehouse and down a short hallway to the second room, where a truck is leaving with what Jane assumes is the weapon of mass destruction. The group fights up some catwalks and then pushes to get outside, fighting to get a view of the truck.

As the group reaches the roof, Hunter identifies the group as Groundhog while looking for the escaping truck. Trent provides cover with a sniper rifle as Russians begin to take shots from multiple locations at the group. The truck is spotted heading west, and Case is left behind on the roof to provide cover as Trent and Jane move out to meet up with another team in the area that is moving to cut off the WMD.
